Detailed Description

To make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a respiratory filter device according to an embodiment of the present invention includes: a shell 1, a face attachment member 2 and a wearing member (not shown in the figure).

The housing 1 comprises an inner housing 11 and an outer housing 12, wherein the inner housing 11 is detachably connected with the outer housing 12 so as to clamp the filter material 3 between the inner housing 11 and the outer housing 12; the face attaching piece 2 is detachably connected to one side of the inner shell 11, which is far away from the outer shell 12, and is used for closely attaching to the face and forming an accommodating space capable of accommodating the mouth and the nose; the wearing piece is detachably connected to the housing 1 for wearing the breathing filter device on the face.

In this embodiment, in specific use, first, the inner housing 11 is separated from the outer housing 12; then, the filter material 3 is placed between the inner shell 11 and the outer shell 12; then, the inner housing 11 and the outer housing 12 are connected together, so that the filter material 3 is clamped and fixed between the inner housing 11 and the outer housing 12; then, the breathing filter device can be worn on the face directly by using the face attaching piece 2 to match with the wearing piece. After the breathing filter device is used for a period of time, the filter material 3 between the inner shell 11 and the outer shell 12 can be taken out, and the filter material 3 can be reused after being replaced by a new filter material 3. Except the filter material 3, other components of the breathing filter device can be recycled after high-temperature disinfection, thereby avoiding the waste of energy and resources and improving the utilization rate of the energy and the resources.

In the above embodiment, the face engaging member 2 is made of food-grade silicone material. In this embodiment, the face attaching member 2 made of food-grade silica gel material can be attached to the face better, the sealing performance is better, when a user inhales air, contaminated gas such as external viruses and the like can not be sucked into the body together due to air leakage around the user, the problems that the sealing is not tight and the filtering is not complete due to the use of hard materials such as ABS (Acrylonitrile Butadiene Styrene), plastics and the like are avoided, and the potential safety hazard of the user is reduced. Simultaneously, after the person of wearing a period, can carry out high temperature disinfection with facial laminating piece 2 to can used repeatedly many times, avoid causing the waste of resource.

In the above embodiment, the face attaching member 2 is integrally formed, so that the processes of secondary processing and secondary assembly are avoided, and the production efficiency and the assembly efficiency of the breathing filter device are improved.

In the above embodiment, the facial attachment member further includes a breather valve 4, as shown in fig. 2, a mounting hole 21 is formed in the facial attachment member 2, and the breather valve 4 is detachably mounted in the mounting hole 21; in the inspiration state, the breather valve 4 is in a closed state; in the exhalation state, the breather valve 4 is in the open state. In this embodiment, the breather valve 4 is a one-way valve, and when a wearer inhales, the breather valve 4 is in a sealed state, so that external air can only be inhaled into the body of the wearer after being filtered by the filter element; when the wearer exhales, the breather valve 4 is the open mode, and the gas such as carbon dioxide that lets the wearer exhale can discharge to the external world through the breather valve 4 fast, has guaranteed that the wearer breathes smoothly not holding out breath.

In the above embodiment, referring to fig. 3, the breather valve 4 includes the main body 41 and the valve plate 42, the center of the main body 41 is provided with the through hole 411 along the axial direction of the mounting hole 21, and the through hole 411 is generally circular, so as to seal the through hole 411; valve block 42 activity sets up in through-hole 411 to close or open through-hole 411, valve block 42 can be made by silica gel, so that valve block 42 has certain elasticity, thereby can closely laminate with circular through-hole 411, with the leakproofness of further guaranteeing breather valve 4, but is not restricted to the specific shape of through-hole 411 and the specific type of valve block 42. When a wearer inhales, the valve plate 42 can close the through hole 411, so that outside air can only enter the accommodating space after being filtered by the filter material 3 and is inhaled into the body of the wearer; when the wearer exhales, the valve plate 42 moves to a set position in the through hole 411 so that the through hole 411 is opened, and therefore, the gas such as carbon dioxide exhaled by the wearer can be rapidly discharged to the outside through the through hole 411.

In the above embodiment, the face adhering member 2 has a first retaining portion, the inner shell 11 has a second retaining portion, and the first retaining portion and the second retaining portion can be engaged with or disengaged from each other to detachably connect the face adhering member 2 to the inner shell 11. In this embodiment, the first engaging portion and the second engaging portion are connected in an engaging manner, so that the convenience of assembling and disassembling the face attaching member 2 and the inner housing 11 is improved.

In the above embodiment, it is preferable that the first catch includes two protrusions 22 and the second catch includes two connection holes 111. When the face attaching piece 2 needs to be connected to the inner shell 11, the two protrusions 22 can be aligned to the two connecting holes 111, and then the two protrusions 22 are slightly pressed to penetrate through the two connecting holes 111; when the face attaching member 2 and the inner housing 11 need to be separated from each other, the face attaching member 2 and the inner housing 11 are respectively held and slightly pulled, so that the two protrusions 22 are separated from the two connecting holes 111. It can be understood that, since the face attaching part 2 is made of a silicone material, the diameters of the two protrusions 22 can be slightly larger than the diameters of the two connection holes 111, so that the two protrusions 22 can be in interference fit with the two connection holes 111, thereby improving the stability of the connection between the face attaching part 2 and the inner shell 11.

In the above embodiment, the two sides of the outer shell 12 are respectively opened with the connecting notches 121, the wearing piece is a head strap, and the two ends of the head strap are respectively detachably connected with the connecting notches 121 on the two sides of the outer shell 12. When the breathing filter device needs to be used, the head strap can be arranged on the outer shell 12, and then the breathing filter device can be worn on the face by the head strap; when the respiratory filter device is not in use, the head strap may be removed from the outer housing 12 for cleaning or heat sterilization. In this embodiment, the head band is used as the wearing member, and compared with a mode of wearing through an ear band, the wearing stability can be improved, and meanwhile, the sealing performance of the face attaching member 2 and the face attachment can be ensured.

In the above embodiments, the head strap is an elastic strap. In this embodiment, the head strap has elasticity, and therefore, the wearing comfort can be improved.

In the above embodiment, the head strap is provided with the adjusting portion, and the adjusting portion can move along the length direction of the head strap to drive the head strap to extend or shorten the set distance along the length direction of the head strap. In this embodiment, utilize regulating part to adjust the length of head bandage, under the travelling comfort's that can improve to wear the prerequisite, can also adapt to different wearers to improve respiratory filter device's suitability.
